Actara 100 g - Thiamethoxam 25% WG - Syngenta

Why Choose This Product? Key Benefits

• 🍃Systemic activity: Thiamethoxam enters plant tissue rather than acting only on the leaf surface. Correct application is still essential.
• 🎯Defined sucking-pest uses: The Indian formulation record includes aphids, hoppers and whiteflies in specific crops, not every insect in every crop.
• 🌾Crop-specific treatment options: Some uses distinguish foliar application from soil drenching. Choosing the correct route prevents a foliar or nursery dose being applied elsewhere.
• ⚖️Weighable WG formulation: Water-dispersible granules are measured in grams for the treated area. Neither sachet count nor tank size defines the field dose.
• 🔄Clear resistance group: Thiamethoxam belongs to IRAC Group 4A. Changing to another thiamethoxam brand does not change the mode of action.

Technical Specifications

How It Works: Mode of Action

Thiamethoxam is a systemic insecticide with contact and ingestion activity. It disrupts insect nerve signalling; it neither fertilises plants nor cures existing viral infection.

1. Reach the plant and pest: Use the approved route: foliar application treats the canopy; a specified soil drench treats the root zone. These methods are not interchangeable.
2. Disrupt nerve receptors: Thiamethoxam competitively modulates nicotinic acetylcholine receptors, interfering with normal nerve signalling in susceptible insects.
3. Control susceptible insects: Disrupted nerve function leads to loss of normal function and death. Correct exposure and susceptibility matter; no fixed knockdown time or control of resistant pests is promised.

Use pest monitoring and integrated management. Account for all earlier Group 4A treatments, including other brands, and select further treatments with qualified local advice and current labels.

Target Crops & Pests

These crop–pest pairings come from the Government of India record for Thiamethoxam 25% WG. This formulation-level guidance does not confirm every use on the current Actara pack; check that pack before treatment.

Shared target rows do not mean shared treatment rates. Rice nursery is a separate soil-drench use. Check each method and crop in the dose table; withheld programmes are explained below.

Dosage & Application Guide

Numerical rows retain methods explicitly identified in the official formulation record and must agree with the current Actara pack. Approximate acre figures use 1 acre = 0.40468564224 hectare; original rates remain the calibration reference.

Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)

Where two crops share a row, dose and water are identical but PHIs remain crop-specific. Follow the named PHI, and confirm the full programme on the supplied pack.

*Per-litre dose: no independent gram-per-litre or pump recipe is supplied. Keep product quantity tied to area and method; do not combine range endpoints to invent a concentration.

*Rice, cotton, okra, mango, wheat, mustard, tea and cumin: the government entries do not explicitly name the application route. Numerical programmes are withheld pending current-pack confirmation of the method and full directions.

*Grapes soil drench: water is specified per vine, not per hectare. Without established vine density and current-pack directions, no acre-scale programme or per-vine product dose is supplied.

Rice-nursery water is originally 250 ml/m². The acre figure converts nursery-bed area only; it is not a foliar-spray volume.

PHI runs from the last application to harvest, not to re-entry or the next spray. No numerical re-entry or rainfast period is established here.

How to Apply: Best Practices

• Confirm product, crop and pest: Use the current Thiamethoxam 25% WG pack directions. Do not substitute rates from 75% SG, seed treatments or combination products. Identify the insect; leaf yellowing alone does not establish a pest or justify treatment.
• Keep methods and measurements separate: Tomato and potato have different foliar and drench rates; rice nursery has its own programme. Weigh granules accurately, not with a household spoon, and measure the treated area. Calibrate equipment and follow the pack’s mixing and agitation procedure.
• Follow each crop’s spray timing: The formulation record starts tomato and brinjal foliar treatment at initial pest appearance. It allows 2–3 repeats according to pest intensity: tomato at 10–15 days, brinjal at 15–21 days. Citrus also starts at initial appearance, with 2–3 repeats at 15–21 days. Confirm these directions on the current pack; they are not a universal schedule.
• Use the separate drench and grape directions: Tomato soil drench is directed to the root zone after transplanting, once per season. Grapes foliar treatment starts at the economic threshold level, with one repeat at 10–15 days if pest severity requires. These timings do not apply to the withheld grape-drench programme.
• Protect people, bees and water: Use label-specified protective equipment. Avoid skin/eye contact, inhalation and drift. Observe flowering and bee-foraging restrictions; prevent water contamination. Record the date for harvest planning.
